Motor: Enabling Multi-Versioning for Distributed Transactions on Disaggregated Memory

Explore a groundbreaking conference talk on Motor, a novel system enabling multi-versioning for distributed transactions on disaggregated memory. Delve into the challenges of memory disaggregation in modern datacenters and learn how Motor addresses limitations of single-versioning designs. Discover the innovative consecutive version tuple (CVT) structure and fully one-sided RDMA-based MVCC protocol that allow for efficient organization of data versions and support fast distributed transactions with flexible isolation levels. Gain insights into Motor's performance improvements, including throughput increases of up to 98.1% and latency reductions of up to 55.8% compared to state-of-the-art systems. Presented by researchers from Wuhan National Laboratory for Optoelectronics and Huazhong University of Science and Technology, this talk offers valuable knowledge for professionals interested in advanced distributed systems and memory management techniques.
